Experiment on post-emergence herbicide, glufosinate in sweet corn production field conducted at the National Corn and Sorghum Research Center during November 2008-January 2010. The objective of this experiment was to study on the efficiency of herbicides and their affect on sweet corn hybrid, Insee 2 variety. The experiment laid out in RCBD, composed of 10 treatments, with 3 replications. The results revealed that weed found in the experiment were purple nutsedge (Cyperus rotundus), wild poinsettia (Euphorbia heterophylla), tropical spiderwort (Commelina benghalensis) and Itchgrass (Rottboellia cochinchinensis). The application of glufosinate at the rate of 800-1,400 g/rai, as post-emergence herbicide gave good weed control of 80-86 percent, and better than glufosinate at the rate of 700 g/rai and hand weeding. They also gave good weed reduction of 39-76 percent. All herbicide treatments were not affect to green ear yield, standard ear weight, and number of good ear of Insee 2.
